Vidalista 20 is a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Vidalista 20 is Tadalafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors.
When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the erectile tissues. At the same time, the veins that normally carry blood away from the penis constrict, trapping the blood inside and causing an erection.
In men with ED, this process is disrupted due to various reasons, such as inadequate blood flow to the penis or excessive blood flow out of the penis. Tadalafil in Vidalista 20 works by inhibiting the action of the PDE5 enzyme, which is responsible for breaking down a substance called cyclic guanosine monophosphate (cGMP). cGMP is essential for the relaxation and widening of the penile arteries.
By inhibiting PDE5, Tadalafil helps to maintain higher levels of cGMP in the erectile tissues. This leads to the relaxation and dilation of the penile arteries, allowing increased blood flow to the penis. As a result, men with ED can achieve and maintain a firmer and longer-lasting erection during sexual stimulation.
It is important to note that Vidalista 20 does not cause an automatic erection. Sexual stimulation is still required to initiate the release of nitric oxide, which in turn triggers the production of cGMP. Vidalista 20 simply helps to enhance the natural erectile response by increasing blood flow to the penis.
